Radiator Alphacool 14473 Brass Copper Steel Black 124mm Width

The Alphacool 14473 radiator is a full-copper high-performance cooling component designed for PC liquid-cooling loops. Built using Alphacool's NexXxoS HPE technology, the radiator combines copper water channels and fins with a compact internal structure to increase coolant contact area and improve heat transfer. Its black finish and dimensions (124 mm width, 511.5 mm depth, 45 mm height) make it suitable for a range of system configurations where effective thermal management is required.

Advantages

The NexXxoS HPE design increases the number of water channels and fin rows, producing a higher thermal conductivity and more efficient use of the cooling surface compared with conventional radiators. Tests indicate up to a 4.5 K performance improvement over standard NexXxoS models under the same test conditions, with possible gains up to 6 K at higher ambient temperatures or fan speeds. The radiator includes recessed patented screw plugs for flush mounting and protective plates under mounting holes to prevent damage to fins and water channels. G1/4" threaded inlet/outlet ports and an additional fill/drain port simplify installation and maintenance, and mounting screws for case and fan installation are provided.

Suitable for

• High-performance PC liquid-cooling loops
• Systems with high waste heat (e.g., overclocked CPUs, powerful GPUs)
• Custom water-cooling builds requiring compact, efficient radiators

How to use

Install the radiator into your case using the included mounting screws, aligning fan and case screw holes. Connect the cooling loop using G1/4" fittings on the designated IN/OUT ports and use the fill/drain port for filling and bleeding air from the circuit. Ensure fans are oriented to provide the desired airflow through the fins and verify there is sufficient clearance for the radiator's 45 mm height. After installation, run the loop and check for leaks at all threaded connections before powering the rest of the system.

Recommendations

For optimal performance, use high-static-pressure fans and ensure the radiator has unobstructed airflow. Periodically inspect mounting points and threaded ports for tightness and check the coolant level; avoid overtightening screws to protect the protective plates and underlying fins.
